1 . Joseph Francis Charles Rock (1884–1962) was an Austrian-American explorer, botanist, and anthropologist(人类学家). For more than 25 years, he travelled extensively through Tibet and Yunnan, Gansu, and Sichuan provinces in China before finally leaving in 1949.

In 1924, Harvard sent Joseph Francis Rock on a treasure hunt through China’s southwestern provinces—the Wild West of their day. But gold and silver weren’t his task : Rock, a distinguished botanist, sought only to fill his bags with all the seeds, saplings, and shrubs he could find. During his three-year expedition, he collected 20,000 specimens for the Arnold Arboretum(阿诺德植物园).

Botany, though, was just one of Rock’s strengths. As an ethnologist(民族学者), he took hundreds of photographs of the Naxi, a tribe in Yunnan province, recording their now-lost way of life for both Harvard and National Geographic, and took notes for an eventual 500-page dictionary of their language. His hand-drawn map of his travels through China’s “Cho-Ni” territory, in the Harvard Map Collection, includes more than a thousand rivers, towns, and mountains indicated in both English and Chinese, and was so well made that the U.S. government used it to plan aerial missions in World War II.

Scientist, linguist, cartographer, photographer, writer—Rock was not a wallflower in any sense. Arrogant and self-possessed, he would walk into a village or warlord’s place “as if he owned the place,” said Lisa Pearson, the Arboretum’s head librarian.

In declaring his successful return under the headline “Seeking Strange Flowers, in the Far Reaches of the World” , the Boston Evening Transcript ran a large photo of the daring explorer wearing in a woolly coat and fox-skin hat. “In discussing his heroism including hair-raising escapes from death either from mountain slides, snow slides and robber armies, he waves the idea away as if it is of no importance.”

The Arboretum and Rock parted ways after 1927, mainly because his trip cost Harvard a fortune—about $900,000 in today’s dollars. Fortunately, many of his specimens, many of his amazing photos, and his great stories remain.

The United Kingdom consists of four countries: England, Wales, Scotland and Northern Ireland. Wales was linked     1     England in the 13th century. In the 17th century England and Wales were joined to Scotland,     2     (form) Great Britain.

They were united in     3     peaceful way. The southern part of Ireland was unwilling to join the English government and broke away to found its own government.

England is the     4     (large) of the four countries and for convenience it is divided     5     (rough) into three zones: the South of England, the Midlands and the North. Most of the population lives in the south, but most of the industrial cities     6     (locate) in the Midlands and the North. It is a pity that the industrial cities which were constructed in the nineteenth century do not attract     7     (visit).

London is the capital city with great historical treasures,     8     is the centre of national government and its administration. It has the oldest port, building and castle     9     (build) by the invaders. Without the historical evidence, we     10     (will) not be able to learn more about the history and culture of the UK.

3 . Now elsewhere in the world, Iceland may be spoken of, somewhat breathlessly, as western Europe's last pristine wilderness. But the truth is, once you're off the ______ track of the low-lying coastal areas where everyone lives, the roads are few, and they're all bad, ______ Iceland's natural wonders have been out of reach and unknown even to its own ________For them the land has always just been there, something that had to be dealt with and, if possible, _______—the mind-set being one of land as commodity rather than land as, well, priceless art on the scale of the " Mona Lisa".

When the opportunity arose in 2003 for the national power company to enter into a 40-year ______ with the American aluminum company Alcoa to supply hydroelectric power for a new smelter （冶炼厂）, those who had been dreaming of something like this for decades ______ the opportunity. For a long time, life here had meant little more than a hut, dark all winter, cold, no hope, children dying left and right, plagues, starvation, volcanoes erupting and destroying all vegetation and livestock, all spirit— a world ______ almost entirely around the welfare of one's sheep and, later, on how good the cod catch was. In the outlying regions, it still largely does.

Ostensibly, the Alcoa project was intended to save one of these dying regions— the remote and sparsely populated east— where the way of life had steadily ______ to a point of desperation and gloom. After fishing quotas (定额) were ______ in the early 1980s to protect fish stocks, many individual boat owners sold their allotments or gave them away, fishing rights ended up mostly in the hands of a few companies and small fishermen were virtually ______. Technological advances drained away even more jobs previously done by human hands, and the people were seeing everything they had worked for all their lives turn out to be ______ and their children move away. With the old way of life doomed, aluminum projects like this one had come to be perceived, wisely or not, as a last chance. "Smelter or death."

The contract with Alcoa would infuse the region with foreign ______, an estimated 400 jobs, and spin-off service industries. It also was a way for Iceland to develop expertise that ______ could be sold to the rest of the world and ______ an economy historically dependent on fish. “We have to live,” Halldor Asgrimsson said. Halldor, a former prime minister and longtime member of parliament from the region, was a driving ______ behind the project. “We have a right to live.”

4 . By the end of the century, if not sooner, the world’s oceans will be bluer and greener thanks to a warming climate, according to a new study.

At the heart of the phenomenon lie tiny marine microorganisms(海洋微生物) called phytoplankton. Because of the way light reflects off the organisms, these phytoplankton create colourful patterns at the ocean surface. Ocean colour varies from green to blue, depending on the type and concentration of phytoplankton. Climate change will fuel the growth of phytoplankton in some areas, while reducing it in other spots, leading to changes in the ocean’s appearance.

Phytoplankton live at the ocean surface, where they pull carbon dioxide(二氧化碳) into the ocean while giving off oxygen. When these organisms die, they bury carbon in the deep ocean, an important process that helps to regulate the global climate. But phytoplankton are vulnerable to the ocean’s warming trend. Warming changes key characteristics of the ocean and can affect phytoplankton growth, since they need not only sunlight and carbon dioxide to grow, but also nutrients.

Stephanie Dutkiewicz, a scientist in MIT’s Center for Global Change Science, built a climate model that projects changes to the oceans throughout the century. In a world that warms up by 3℃, it found that multiple changes to the colour of the oceans would occur. The model projects that currently blue areas with little phytoplankton could become even bluer. But in some waters, such as those of the Arctic, a warming will make conditions riper for phytoplankton, and these areas will turn greener. “Not only are the quantities of phytoplankton in the ocean changing. ” she said, “but the type of phytoplankton is changing.”

And why does that matter? Phytoplankton are the base of the food web. If certain kinds begin to disappear from the ocean, Dutkiewicz said, “it will change the type of fish that will be able to survive.” Those kinds of changes could affect the food chain.

Whatever colour changes the ocean experiences in the coming decades will probably be too gradual and unnoticeable, but they could mean significant changes. “It’ll be a while before we can statistically show that the changes are happening because of climate change,” Dutkiewicz said, “but the change in the colour of the ocean will be one of the early warning signals that we really have changed our planet.”

1. What are the first two paragraphs mainly about?

A．The various patterns at the ocean surface.

B．The cause of the changes in ocean colour.

C．The way light reflects off marine organisms.

D．The efforts to fuel the growth of phytoplankton.

2. What does the underlined word “vulnerable” in Paragraph 3 probably mean?

A．Sensitive.

B．Beneficial.

C．Significant.

D．Unnoticeable.

3. What can we learn from the passage?

A．Phytoplankton play a declining role in the marine ecosystem.

B．Dutkiewicz’s model aims to project phytoplankton changes.

C．Phytoplankton have been used to control global climate.

D．Oceans with more phytoplankton may appear greener.

4. What is the main purpose of the passage?

A．To assess the consequences of ocean colour changes.

B．To analyse the composition of the ocean food chain.

C．To explain the effects of climate change on oceans.

D．To introduce a new method to study phytoplankton.

5 . In the 1960s, while studying the volcanic history of Yellowstone National Park, Bob Christiansen became puzzled about something that, oddly, had not troubled anyone before: he couldn’t find the park’s volcano. It had been known for a long time that Yellowstone was volcanic in nature — that’s what accounted for all its hot springs and other steamy features. But Christiansen couldn’t find the Yellowstone volcano anywhere.

Most of us, when we talk about volcanoes, think of the classic cone(圆锥体) shapes of a Fuji or Kilimanjaro, which are created when erupting magma(岩浆) piles up. These can form remarkably quickly. In 1943, a Mexican farmer was surprised to see smoke rising from a small part of his land. In one week he was the confused owner of a cone five hundred feet high. Within two years it had topped out at almost fourteen hundred feet and was more than half a mile across. Altogether there are some ten thousand of these volcanoes on Earth, all but a few hundred of them extinct. There is, however, a second less known type of volcano that doesn’t involve mountain building. These are volcanoes so explosive that they burst open in a single big crack, leaving behind a vast hole, the caldera. Yellowstone obviously was of this second type, but Christiansen couldn’t find the caldera anywhere.

Just at this time NASA decided to test some new high-altitude cameras by taking photographs of Yellowstone. A thoughtful official passed on some of the copies to the park authorities on the assumption that they might make a nice blow-up for one of the visitors’ centers. As soon as Christiansen saw the photos, he realized why he had failed to spot the caldera: almost the whole park—2.2 million acres—was caldera. The explosion had left a hole more than forty miles across—much too huge to be seen from anywhere at ground level. At some time in the past Yellowstone must have blown up with a violence far beyond the scale of anything known to humans.

1. What puzzled Christiansen when he was studying Yellowstone?

A．Its complicated geographical features.

B．Its ever-lasting influence on tourism.

C．The mysterious history of the park.

D．The exact location of the volcano.

2. What does the second paragraph mainly talk about?

A．The shapes of volcanoes.

B．The impacts of volcanoes.

C．The activities of volcanoes.

D．The heights of volcanoes.

3. What does the underlined word “blow-up” in the last paragraph most probably mean?

A．Hot-air balloon.	B．Digital camera.
C．Big photograph.	D．Bird’s view.

6 . Every year about 40,000 people attempt to climb Kilimanjaro, the highest mountain in Africa. They _______ with them lots of waste. The _______ might damage the beauty of the place. The glaciers(冰川) are disappearing, changing the _______ of Kilimanjaro.

However, I soon _______ that much has changed since the days of disturbing reports of _______ among tons of rubbish. I find a _______ mountain, with toilets at camps and along the paths. The environmental challenges are _______ but the efforts made by the Tanzania National Park Authority seem to be _______.

The best of a Kilimanjaro ________, in my opinion, isn’t reaching the top. Mountains are ________ as spiritual places by many cultures. This ________ is especially evident on Kilimanjaro as ________ go through five ecosystems(生态系统) in the space of a few kilometers. At the base is a rainforest. It ends abruptly at 3, 000 meters, ________ lands of low growing plants. Further up, the weather ________ — low clouds envelope the mountainsides, which are covered with thick grass. I ________ twelve shades of green from where I stand. Above 4, 000 meters is the highland ________: gravel(砾石), stones and rocks. ________ you climb into an arctic-like zone with ________ snow and the glaciers that may soon disappear.

Does Kilimanjaro ________ its reputation as a crowded mountain with lines of tourists ruining the atmosphere of peace? I found the opposite to be true.

Built over 2,000 years ago in     3     is now Sichuan Province in Southwest China，this amazing engineering achievement is still playing a crucial role in irrigating farms and providing water resources for more than 50 cities in the province.

In ancient times, the region in which Dujiangyan now stands     4    (threaten) by frequent flooding from the Minjiang River. Li Bing, a local official of Sichuan Province at that time, together with his son, decided to construct an irrigation system on the Minjiang River     5    (prevent) flooding. After many studies, they found the     6     (simple) solution was to build a dam, but this would have ruined the Minjiang River. So instead Li designed a series of     7    (channel) built at different levels along Mount Yulei that would take away the floodwater while leaving the river flowing     8    (natural). Better still, the extra water could be directed to the dry Chengdu Plain,     9    (make) it suitable for farming.

Classical Chinese garden design aims to create a natural landscape on a small scale and emphasize the perfect harmony between man and nature.

A Chinese garden     1    (be) like a scroll (卷轴) painting,     2    (show) a series of carefully composed scenes. New views are revealed as one walks along the pathways. In the gardens,     3     most frequently meets the eye is winding paths that seemingly lead to nowhere. There, a path seems to end, but all of     4     sudden, a new world is rolled out before you: pavilions (亭子), rock formations, spring waters—all combined to provide a pleasant surprise! At the     5    (enter) to a Chinese garden, there is usually a huge stone or wall     6    (use) to screen your view so as to later produce unimaginable delight when you turn around the wall. A Chinese garden may have windows on all     7    (it) four walls. And it is     8    (interest) that, through the windows, visitors may see different views at different angles, and thus the composition of the garden becomes enlarged.

A Chinese garden is where culture is both created and enjoyed. All plants mark the shift of the     9    (season). Similarly, water, a symbol of the ever-changing,     10     rocks, a symbol of the eternal (永恒的), create a harmonious balance of nature’s yin and yang.
